推荐答案
您的代码只包含一堆全局常量。你不能在 VB.NET 代码中使用全局变量，所以你必须实现一个变通方法（例如，参见：vb.net全局常量 [ ^ ]）。理解之后，自动（或半自动）转换这样的代码非常简单。
Your code just contains a bunch of global constants. You cannot have globals in VB.NET code, so you have to implement a workaround (see, for instance, here: "vb.net global constant"[^]). Once that is understood, it is really simple to automatically (or semi-automatically) convert such a piece of code.
创建一个静态类并在其中添加所有这些常量。在代码的其余部分使用class_name.constant_name。
Create a static class and add all these constants in it. Use class_name.constant_name in the rest of your code wherever they are used.
